PATENT FFICEQ HUGO NElVMAN, OF NEWT YORK, N. Y.

LANTERN-SLIDE-MOVING DEVICE.

SPECIFICATION forming part of Letters Patent No. 590,903, dated September 28, 1897.

Application filed September 22, 1896. Serial No. 606,674z- (N model.)

To all whom, it ntay concern.-

Beit known that I, HUGO NEWMAN, of New York, (Fordham Heights,) in the county and State of New York, have invented a new and This invention relates to devices for moving slides to and from a projecting ormagic lantern; and the object is to provide a device whereby a lecturer or other party at a distance from the lantern may cause a series of slides to bemoved consecutively in front of the lens of the lantern, thus placing the movement of the slides directly under the control of the lecturer and dispensing with the usual attendant.

I will describe a lantern-slide-moving device embodying my invent-ion, and then point out the novel features in the appended claims.

Reference is to be had to the-accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of a device embodying my invention, a portion of the same being broken away to more clearly show other parts. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a perspective view of a magazine for slides. Fig. 4 is a vertical section thereof. Fig. 5 is a detail showinga device for engaging with a slide for moving it. Fig. (3 is a similar view, but showing thev engaging device in another position. Fig. 7 is a vertical section of a slide-receiver embodied in the invention, and Fig. Sis a section on the line 8 8 of Fig. 7.

The invention comprises a boX or magazine 1, having extended longitudinally ofit 'a downwardly and forwardly inclined floor 2,

upon whichthe lower edges of the slides 3' rest. At the forward end a vertical walli extends upward from the inclined floor 2. The space below the floor 2 is designed to receive a motor for moving the plates, as will hereinafter bedescribed.

The forward portion of the slide-magazine 1 communicates with a lateral guideway 5, which, as here shown, communicates with a guideway 6, provided with an opening 7, through which the illustrations are projected. The section 5 of the gnideway is shown, as

telescoping into the section 6. Therefore it These guide-rods 9 and 10 are secured at one end to the front wall or to the front of the guidewaysection 5 and extend a short distance beyond theside of the magazine and are then re-. turned to a connect'on with said side of the magazine. Mounted to slide on these guiderods 9 and 10 is a plate'll, having an opening', 12 through it and having secured to its front side a bar 13. Pivoted onthis bar 13 is a shifting finger 14. This shifting finger l4c'extends through the opening 12 and at its inner end is curved forward and rearward, so that it may be extended through the slot opening 8 in the front wall 4 of the magazine 1. A spring 15, attached at one end to the shifting finger 14 and at the other end to the plate 11, serves to normally hold said finger with its inner end within the slot 8 and against the edge of the lantern-slide.

The outer portion of the sl1iftingfinger 1i is provided with a ring 16, which engages loosely around a lever- 17, extended downward and mounted to rock in a bearing 18, secured to the bottom 19 of the magazine 1. This lever 17 terminates in a crank-arm 20, and from this crank-arm 20 a link 21 extends to a connection with a rod 22, extended from an armature 23, coacting with electromagnets 24. The

electromagnets are in connection with binding-posts 25, from which line-wires 20 and 27 may extend to any desired point where a controlling-switch may be placed. it is obvious that when the electromagnets 24 are energized the armature 23 will be drawn downward, and by turning the crank-arm 20 the lever 17 will be turned, and the movement of this lever 17 will cause the plate 11 to move longitudinally Y Arranged above this slot-opening Sis a guide-rod 9, and below said slot-opening is'another guide-rod 10.

of the guide-rods 9 and 10, and theinner end of the shifting finger 14, en gaging with a slideplate, Will move the same into-the guid'eway. Upon the return movement of said'lever the shifting finger 14 will be turned on its pivot, with the inner end engaging against the surface of a slide-plate in the magazine, and of course after the shifting fingen shall have lantern is placed.

passed the said plate in the magazine the spring will move the finger so that its inner end will engage with the front slide in the magazine, and when this second plate is moved forward it will engage against the first plate and move said first plate in line with the opening 7, behind which the lens of the When the eleetromagnets 2i are deenergized, the armature 23 may be raised by means of a spring 28, and this upward movement of the armature 23 will shift the lever 17 to its normal position.

It is desirable before the slides are moved across the opening 7 that a closure shall be moved across said opening. This closure c0nsists of two strips 20 and of flexible material. One edge of the strip 20 is secured to the lower portion of the guideway 6 and the other edge is secured to a rod 31, extended from a shaft One edge of the strip 30 is similarly attached to the guideway 6 and at the other end to a rod 33, extended from a shaft 34:. On the shaft 32 is a pinion 35,1neshing with a pinion 36 on the shaft 3i. Meshing with the pinion 35 is a segment-gear 37, and on the shaft of this segment-gear 37 is a finger 38, designed to be engaged by a pushrod 30, extended through a suitable guide and having a slide connection 4:0 with the lever 17.

The object in extending the guide-rods 0 and 10 beyond the side of the magazine 1 is to provide for a sufficient initial movement of the lever 17 to close the closures or curtains 2H and 30 before the shifting finger 1t engages with a slide in the magazine. Therefore it will be seen that upon the initial movement of said lever the p ush-rod 3f), engaging with the finger 38, will rock the segment-gear 37, and this segment-gear 37 will rotate the pinion 35, and the pinion 35 will rotate the pinion 36 in the opposite direction, so that the closures or curtains will be moved into the position indicated in dotted lines in Fig. 1. Upon the return movement of the lever .17 a spring 41, engaging at one end with the segment 37 and at the other end with a fixed portion of the guideway, will cause the segment 37 to move to its normal position to open the closures or curtains.

The several plates are consecutively dis charged from the guideway G into a receiver 4-2, consisting of a suitable box. The guideway 6 has a downwardly-extendedportion 1L3, which extends through an opening in the top wall'of the receiver and communicates with the interior of said receiver. Springfingers ll may be attached to the lower end of the downwardly-extended portion &3 and adjusted to bear more or less upon a slide 3, as may be desired, so as to prevent its falling too rapidly.

Movable on vertical guide-rods 45, within the receiver 42, is a carriage 46. Mounted to swing on a rod supported by the carriage or plate 46 is a tilting table 47. This tilting table 47 extends transversely of the receiver and is designed to support the slides 3 while ,the same are being carried downward. The table i7 is held. yieldingly in its normal or substantially horizontal position by means of a spring atS, engaging at one end with. the plate 46 and at the opposite end with a back plate 49, extended upward from the tilting table 47. Rods 50 extend upward from the plate 46, and at their upperends these rods 50 are turned forward and provided with eyes 51, with which are loosely engaged the side members 52 of the yoke From one of the side members 52 of the yoke 53 a tripping-rod 54 extends downward through a guide-eye 55 on the plate at and the lower end of this trip-rod projects below the lower edge of said plate 46. From the plate 46 a spring 56 extends upward to a connection with the top of the receiver $2. This spring 56 must be sufliciently flexible to allow the plate 5L6 and the parts carried thereby to move downward when aided by the weight of the slide engaging on the table l7;

In operation when a slide 3 strikes the tilting table 47 the carriage comprising the plate 46 and table l7 will move downward, and when the slide shall have been released from the spring-fingers M it will tip forward, so that its upper edge will engage with the yoke 53, and on the continued downward movement of the carriage the end of the trippingrod 54 will engage with the lower wall of the receiver 42 or with the top slide that may have been previously deposited therein, and then as the carriage continues, the trip-rod 5% remaining stationary, the yoke 53 will be swung upward out of engagement with the slide, so that said slide may fall downward and be deposited in the receiver.

To relieve the falling slide from shock that would be liable to break it, I preferably eniploy a spring-yielding plate 57, secured at its lower end to the front wall of the receiver, which in this instance is a hinged door, the said plate being inclined upward and inward. As the carriage moves upward under the influence of the spring 56 the table 47 will tilt sufficiently to disengage itself from the edge of the slide, and after such disengagement the spring 48 will return it to its normal position. If desired, the bottom of the receiver 42 may be provided with an inclined platform 58.

Having thus described my invention, I claim as new and desire to secure by Letters Patent--- 1.
